qcow2: Order concurrent AIO requests on the same unallocated cluster
When two AIO requests write to the same cluster, and this cluster is
unallocated, currently both requests allocate a new cluster and the second one
merges the first one when it is completed. This means an cluster allocation, a
read and a cluster deallocation which cause some overhead. If we simply let the
second request wait until the first one is done, we improve overall performance
with AIO requests (specifially, qcow2/virtio combinations).
This patch maintains a list of in-flight requests that have allocated new
clusters. A second request touching the same cluster is limited so that it
either doesn't touch the allocation of the first request (so it can have a
non-overlapping allocation) or it waits for the first request to complete.

qcow2: Fix metadata preallocation
The wrong version of the preallocation patch has been applied, so this is the
remaining diff.
We can't use truncate to grow the image file to the right size because we don't
know if metadata has been written after the last data cluster. In this case
truncate would shrink the file and destroy its metadata. Write a zero sector at
the end of the virtual disk instead to ensure that the file is big enough.

mips malta: Fix fdc regression and use qdev for i8042 setup

breaks MIPS Malta:
Tried to create isa device isa-fdc with no isa bus present
Fix this by creating an isa bus for piix4.
This change also requires some more qdev related changes
(similar changes were applied to pc.c) and allows
cleaning of piix3/piix4 code.

With this commit monitor_handle_command() will be able to setup a
QDict with arguments to command handlers.
However, the current 'args[]' method is still being used, next
changes will port commands to get their arguments from the dictionary.
Two changes are worth noting:
1. The '/' argument type always adds the following standard keys in the
dictionary: 'count', 'format' and 'size'. This way, the argument
name used in the 'args_type' string doesn't matter
2. The optional argument type '?' doesn't need to pass the additional
'has_arg' argument, hanlders can do the same check with qdict_haskey()

monitor: New format for handlers argument types
Current handlers argument types, as defined in qemu-monitor.hx file,
are a sequence of chars where each one represents one argument type
of the command handler. The number of chars is also used to know how
many arguments a given handler accepts.
This commit defines a new format, which makes mandatory the use of
a name for each argument.
For example, do_eject() command handler is currently defined as:
{ "eject", "-fB", do_eject, ... }
With the new format it becomes:
{ "eject", "force:-f,filename:B", do_eject, ... }
This way the Monitor will be capable of setting up a dictionary, using
each argument's name as the key and the argument itself as the value.
This commit also adds two new functions: key_get_info() and
next_arg_type(), both are used to parse the new format.
Currently key_get_info() consumes the 'key' part of the new format and
discards it, this way the current parsing code is not affected by this
change.
